I'd file "measles party" under "child abuse" but I just press buttons for a living.

OTOH, if their sons contract mumps as adults, these women--there are no fathers in the article--may have removed themselves from the gene pool. (One of my friends in Iowa caught the mumps in that epidemic--not a college student, just had the misfortune to sit in a waiting room with an infected individual while his immune system was compromised by leukemia. He's fine now, but apparently orchitis is unpleasant, and I'm waiting for the phone call where he and his wife are devestated by sperm count...)
